Is y = 99 a solution to this equation?

Question

11 =
y
9
Yes or no

Answer 1

To determine if \( y = 99 \) is a solution to the equation

\[ 11 = \frac{y}{9}, \]

we will substitute \( y \) with \( 99 \):

\[ 11 = \frac{99}{9}. \]

Now calculate \( \frac{99}{9} \):

\[ \frac{99}{9} = 11. \]

Thus, we have:

\[ 11 = 11. \]

Since both sides of the equation are equal, the answer is yes, \( y = 99 \) is a solution to the equation.
